Title: An improved device for delivering gummed paper
IPC: B65H35/00
Filed: 1935-11-20
Abstract: 466,036. Delivering adhesive strips. BOYDEN, P. Nov. 20, 1935, No. 32209. [Class 73] [Also in Group XVI] An apparatus for delivering gummed paper for wrapping purposes in which the paper unwound from a roll is gummed prior to being severed for use is constructed with means for projecting a plain strip to facilitate operation of the device by pulling on the strip, and with means for automatically stopping the feed after the delivery of strips of predetermined lengths. The roll 2 is placed over a vertical peg in a casing 1, and the web is led over a vertical guide roll, and an inclined roll 6 to the main casing which may contain a printing-couple 42, 9 as well as a gumming roller 13 and a serrated cutting knife 17. A guide roll 8 directs the web to the impression roller 9 and the printed web passes between guide plates 14, 15 which are in the form of circular arcs having as centre the axis 21 of a spring-controlled lever 22 formed at its upper end with a fixed gripper pad capable of moving in a circular slot formed in the plates 1, 15. The upper gripper member 26 is carried by two levers 25, 27 normally raised by a spring 32 and pivoted at 28 to a lever 29, which is depressed by operation of a lever 53 formed with a further lever 37. Downward movement of the levers 25, 27 cause the gripping of the web and then its advancement by an amount of about two inches. A roll 16 and incline 15 guide the web clear of the roller 13 so that an ungummed strip is provided to allow of withdrawal of the web by pulling. The amount of web delivered may be determined by a stop device which can be set to permit of the delivery of say 10 inches of web, 20 inches, or may be set to permit of free operation. The normal upward position of the levers 35, 37 is determined by a stop in the form of an eccentrically mounted equilateral triangular stop 55, which can be set to vary the position of a lever arm 53 formed with a lug 54 which can stop the rotation of the printing-couple by engaging one or both of two lugs on a bar 52 eccentrically mounted on a wheel 51 geared to the printing-roller 42, or the stop can be set so that the printing- couple is free at all times. This mechanism for permitting the feed of predetermined lengths may be used independently of the printing mechanism.

Filed: 1974-07-24
Abstract: 1461644 Charge-coupled devices FAIRCHILD CAMERA & INSTRUMENT CORP 24 July 1974 [28 Dec 1973] 32719/74 Heading H1K In a process for producing a CCD in which the gate electrode structure is precisely aligned with barrier regions defining the boundaries of adjacent potential wells the regions are formed by ion implantation in such a manner that the surface areas of the structure overlying the regions are different from the rest of the surface thereby enabling them to be identified in subsequent steps for forming the electrodes. In the embodiment described a layer 24 of thermal oxide (Fig. 7) and deposited layers of silicon nitride 26 and doped polysilicon 28 are successively formed on one face of a P type silicon wafer and arsenic or phosphorous ions are implanted to form an N type layer 21 in the wafer before or after deposition of the polysilicon. A further layer of silicon nitride 30 is then deposited and formed into a mask with parallel elongate apertures by photoresist and etching steps. Boron ions are next implanted through the apertures to form N-barrier regions 44, and the surface of the polysilicon in the apertures oxidized 54. The areas between alternate pairs of barrier regions are photoresist masked, the exposed nitride etched, the alternate barrier regions similarly masked and the exposed oxide regions 54 etched away, to leave areas 74, 76 (Fig. 10) of polysilicon exposed. After etching away the exposed polysilicon alternative procedures are suggested. In the first the edges of the remaining polysilicon strips constituting electrodes of one phase are oxidized and aluminium deposited overall and patterned to form a strip normal to the polysilicon strips and constituting the electrodes of the other phase. In the second procedure the residual nitride is etched away and oxide formed over the exposed polysilicon prior to deposition of the aluminium.

Title: Superconductor circuitry
IPC: G06F9/32
Filed: 1959-09-29
Abstract: 935,207. Circuits employing superconductive elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 29, 1959 [Dec. 29, 1958], No. 33043/59. Class 40 (9). [Also in Group XIX] A superconductor circuit comprises a number of bi-stable stages in which each stage causes the next to assume one stable state and may be switched to the other state by a succeeding stage. Preferably each stage is coupled to a number of other stages through a programming device which is settable so that the stage may be switched by either the second, fourth or sixth succeeding stage, or by the commencement of the next cycle. Fig. 1 shows a distributer having stages 11B, 12A ... 17B, 18A, a typical stage 14A comprising parallel current paths 14a, 14b between terminals 14c and 14d. The state of the stage is detected by testing the resistance of cryotron gate conductor 14f; if the conductor is resistive, due to current flowing in path 14b, which includes a control coil about the conductor, the stage is considered on. The path 14a includes a cryotron gate conductor K14e, the control coil of which is included in the path 13b of the preceding stage. Thus when stage 13B is switched on and current from source 10A flows in the path 13b cryotron gate K14e is sent resistive, and after a delay dependent on the circuit constants current flowing in path 14a is switched to path 14b. The path includes the control coil of cryotron gate K14f, the control coil of cryotron gate K12g, the conductor of which is in the path 12b of stage 12A, the conductor of cryotron gate K14g and the control coil of cryotron gate K15e. The action of current flowing in path 14b is thus to turn off stage 12A by sending path 12b resistive and turn on stage 15B by sending path 15a resistive. Thus each stage is on until the second following stage is switched on. A cycle is initiated by applying start pulses to the control coils indicated in the Figure. The arrangement shown requires two current sources but a circuit needing only one source is described (Fig. 2). The programming device described (Fig. 3, not shown), consists in providing the path 14b, say, with several alternate branches including control coils of cryotron gates in the " b " paths of the second, fourth and sixth preceding stages, and a branch which leads directly to the 14d terminal. By energizing control coils of cryotron gates in all but one of these branches the length of time that a stage is switched on may be determined, or the stages when switched on may be caused to remain on until the end of a cycle. A closed ring may be constructed by connecting the last stage of the distributer to the first.
